Analysis of Communication System Based on Multipath Fading and Simulation

According to learning communication system,three kinds of channels are studied:additive white gaussian channel,multipath rayleigh fading channel and rician fading channel.The result of analyzing and simulating the bit error rate of the different communication channels shows that the bit error rate of multipath rayleigh fading channel is higher than that of additive white gaussian channel and rician fading channel which reduces the performance ability of communication system.Simulating on direct sequence spread spectrum which bears the characteristic of anti-multipath fading follows that direct sequence spread spectrum can deal with the influence of multipath fading in communication system.
